To all whom it may concern:

Be it known that I, SARAH FRANCES DYKES, a citizen of the United States,residing at Hawkinsville, in. the county of Pulaski and State ofGeorgia, have invented certain new and useful Improvements in MechanicalMotors for Operating Ghurns; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The invention relates to mechanism adapted to oscillate a creamreceptacle for the purpose of churning and also to serve as a mechanicalmotor for general purposes.

The said invention consists in the construction and combination of partshereinafter more particularly set forth and claimed.

In the accompanying drawings: Figure 1 represents a side view inelevation of a machine embodying my invention; Fig. 2 represents adetail side elevation of the suspended spring casing, one side thereofbeing removed to exhibit the inclosed spring; Fig. 3 represents a detailplan view of the platform or base for the receptacle and proximateparts; Fig. 4 represents a sectional view of the machine taken in avertical plane parallel to that of Fig. 1, the cream receptacle beingomitted. Two diversely inclined positions of oscillation of the platformand spring casing and intervening swinging parts are shown in dottedlines. Fig. 5 represents a vertical section on the line 55 of Fig. 4,the pivot studs or gudgeons being left unsectioned; and Fig. 6represents a detail view of the anchor-form escapement-pawl and thefixed arm engaging the upper end of its long stem.

The supporting table 1 has widely diverging legs, for convenience ofaccess to the diskform spring-casing 4, which is suspended by a frameconsisting mainly of two parallel bars 3, connected by transverse rods22 and passing down through an opening 2 in the table top from arock-shaft 8 journaled in a supplemental stand 6, which is supported bysaid table. A platform 7 is mounted on said shaft, these parts 3, 7 and8 rocking Specification of Letters Patent.

together, but having no individual motion. The casing 4 accompaniestheir oscillation, but, to cause it, also turns on its arbor or shaft 25(see Fig. 2) with a step by step movement from left to right, caused bythe clock-spring 17, within said casing, which is attached at its endsto said casing at 20 and said arbor 25 respectively, and controlled bythe engagement of an anchor-form escapement pawl 23 with a circularseries of spur teeth 21 on the periphery of said casing. This spring maybe wound by a thumb piece or winding head 5 on one protruding end ofsaid arbor, which is also provided with a ratchet wheel 18 engaged by aretaining pawl 19 (Fig. 1). The pawl 23 consists of a preferablyintegral long upwardly extending arm or stem and a head having pallets ab at its ends extending downward to be acted on by said teeth 21 andengage them. At the junction of the lower end of said stem with themiddle of said head this pawl is provided with lateral pivot studs 0,whereby it is journaled in bars 3, the pawl, excepting said pallets andthe proximate terminal parts of the head, being located between them.The long stem of this anchor escapement-pawl is attached to a stud orbent end of a horizontal arm (Fig. 6), 24 mounted on stand 6 andengaging the edge of an opening in plate 26 thereof by means of a notch27 in said arm which notch is long enough to permit some play of thepawl 23 on its pivot 0 for preventing strain and facilitating detachmentof said arm at will. The pivotal connection of parts 23 and 24 isvertically below shaft 8 making the stem or pawl 23 shorter than bars 3.

Any convenient object requiring oscillation may of course be mounted onplatform 7, but I have shown it as carrying a cream receptacle 13,inasmuch as the primary purpose of the mechanism herein described is tooscillate and churn the contents thereof, producing butter. Thisreceptacle has a mouth 14 on its top and a hole 15 in its side fordrawing oif the butter-milk after churning. It is also held in positionby straps 10, which have button-holes 12 (Fig. 4) for engaging studs 16on top of said receptacle, said straps being passed through keepers 11on the in place.

under side of said platform. Spacing springs 9 may surround shaft 8 onboth sides of the platform (Fig. 3) to hold. the parts the leftof palletZ) to act thereon, moving said pallet upward and outward. As theattachment of the upper end of the stem of pawl 23 to fixed arm 24prevents said pawl from moving independently on its own pivot 0, exceptslightly (to free the tooth) by reason of the points of attachment ofthe upper ends of said pawl and said bars 3, it follows that the bars 3must rock with said pawl to permit the said requisite movement of palletb. The platform 7, as already explained participates in such motion,carrying with it the cream receptacle 13 or whatever else it may supportto the left, the bars 3 swinging to the right. Then the pallet Z) isthus made to rise sufiiciently to free such tooth, as shown in dottedlines in the right of Fig. 4, the spring casing 4 turns for theperipheral interval between two teeth, bringing the next tooth to theleft of pallet a into contact therewith, moving it upwardly andoutwardly. The stem of the pawl 28 being attached at its upper end to anarm 24 as above stated the pawl has no movement independent of said bars3, except a ver 1 slight movement to allow said pallets to rise and freethe teeth. Therefore in rising upwardly and outwardly the pallet a willturn the pawl 28 slightly on its pivot, its influence being to force theswinging parts to the left, that is in the reverse direction than thepallet 6, these two pallets being on different sides of vthe pivot 0.Thus when the teeth bear against pallet b the tendency will be to forcethe swinging parts to the right and rock the platform and whatsoever itmay support to the left and when they bear against the pallet a thetendency will be to force the swinging parts to the left and rock theplatform and whatsoever it may support to the right. 7 When the extremeend of the swing is reached, that is when one of the, pallets rises overa tooth the tooth next to the left of the other pallet will en gage thesame, forcing it upward and outward and reversing the direction ofmovement, thus the reciprocating movement is "continuous until thespring runs down.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In combination with a rotary springcasing provided with peripheralteeth and a spring within said casing for turning the same, a pivotedsuspending frame for said casing adapted to permit and accompany itspendulum-like oscillation, apawl pivoted in said frame, engaging saidteeth and arranged and adapted to carry the said frame and casing withit in its oscillating movement and means for supporting a receptaclemoving with said frame, pawl and casing substantially as and for thepurpose set forth.

*2.
